What Is Mild Hyperbaric Oxygen Therapy? Inside the Vitaeris 320
Updated October 20, 2026 · 3 min read
Hyperbaric oxygen therapy sounds intense. Pressurized chambers. Oxygen. Medical equipment.
But the experience at iCRYO Mauldin is surprisingly calm, thanks to a gentler approach called mild hyperbaric oxygen therapy in the soft-shell OxyHealth Vitaeris 320.
Here's what mild hyperbaric therapy is, how the Vitaeris 320 works and what to expect.

What Does "Mild" Mean?
Hyperbaric pressure is measured in atmospheres absolute (ATA):
- 1.0 ATA is normal air pressure at sea level
- About 1.3 ATA is typical for mild, soft-shell chambers
- Higher pressures are used in hospital chambers for specific medical conditions
"Mild" simply means the chamber uses a gentler pressure that's well suited to wellness and recovery routines.
Meet the Vitaeris 320
The Vitaeris 320 is one of OxyHealth's best-known soft-shell chambers.
- Soft-shell design: made of durable, flexible material that inflates as it pressurizes
- 32-inch diameter: room to lie back comfortably
- About 4 psi: roughly 1.3 ATA
- Zippered entry and viewing windows: so you can see out and our team can see in
How Mild Hyperbaric Therapy Works
- The chamber gently pressurizes around you
- The added pressure helps more oxygen dissolve into your blood plasma
- More oxygen can reach your tissues while you rest

What a Session Feels Like
- Screening: we review your health history first
- Settle in: lie down inside the Vitaeris 320, and we zip the chamber closed
- Pressurization: the chamber inflates and your ears may feel full; swallowing or yawning helps
- Relax: rest, listen to music or nap
- Depressurization: pressure slowly returns to normal before we unzip the chamber
Most sessions last about an hour, and there's no downtime afterward.
Mild vs. Hospital Hyperbaric Therapy
| Mild (Vitaeris 320) | Hospital HBOT | |

| Chamber | Soft-shell, inflatable | Rigid medical chamber |
| Pressure | About 1.3 ATA | Higher pressures |

Mild hyperbaric therapy is a wellness tool. It isn't a substitute for medical treatment.
